Defining Concentric Geometric Constraints
Use the GcConcentric command to make the center points of Arcs, Circles, Ellipses, or elliptical Arcs to coincide.
To define concentric Geometric Constraints:
- Click Constraints > Geometric Constraints > Concentric (or type GcConcentric).
- Specify the first entity (Circle, Arc, Ellipse, elliptical Arc, or PolyLine arc).
- The first entity is the one that maintains position.
- Specify the second entity (Circle, Arc, Ellipse, elliptical Arc, or PolyLine arc).
- The second entity moves so that its center point coincides with the center point of the first entity.
When you specify a PolyLine arc as the second entity, only the specified arc segment is made concentric to the first entity; the geometry of the PolyLine changes instead of moving entirely.
